Description

La présente invention concerne de nouveaux adjuvants pour compositions vaccinales ainsi que des compositions comprenant au moins un antigène, notamment un antigène d'origine virale, bactérienne ou parasitaire et au moins un adjuvant.The present invention relates to novel adjuvants for vaccine compositions as well as compositions comprising at least one antigen, in particular an antigen of viral, bacterial or parasitic origin and at least one adjuvant.

Le développement de vaccins inactivés ou contenant des antigènes purifiés est de plus en plus important, car il permet d'éviter les effets secondaires indésirables. Cependant, l'amélioration de la qualité des antigènes se fait au détriment de leur caractère immunogène. C'est pour cette raison qu'ils sont associés à des adjuvants d'immunité.The development of vaccines inactivated or containing purified antigens is increasingly important because it avoids undesirable side effects. However, the improvement of the quality of the antigens is to the detriment of their immunogenic character. It is for this reason that they are associated with immunity adjuvants.

Les adjuvants d'immunité sont des produits qui augmentent les réactions du système immunitaire, lorsqu'ils sont administrés en présence d'antigènes d'origine virale, bactérienne ou parasitaire. Ils provoquent l'apparition massive de macrophages au site d'injection, puis dans les nodules lymphatiques, accroissent la production d'immunoglobulines spécifiques, les anticorps, et stimulent de nombreuses cellules impliquées dans les mécanismes de la défense immunitaire.Immune adjuvants are products that enhance immune system reactions when administered in the presence of antigens of viral, bacterial or parasitic origin. They cause the massive appearance of macrophages at the injection site, then in lymphatic nodules, increase the production of specific immunoglobulins, antibodies, and stimulate many cells involved in the mechanisms of immune defense.

Ces adjuvants sont de natures diverses. Ils peuvent par exemple consister en des mélanges d'huiles et de tensioactifs conduisant à des vaccins sous forme de liposomes ou d'émulsions.These adjuvants are of various natures. They may for example consist of mixtures of oils and surfactants leading to vaccines in the form of liposomes or emulsions.

Les adjuvants de Freund sont très efficaces ; ils résultent de l'association d'une huile minérale et d'un ester de mannitol contenant ou non une mycobactérie tuée.Freund's adjuvants are very effective; they result from the combination of a mineral oil and a mannitol ester containing or not killed mycobacterium.

Les vaccins réalisés par mélange à parts égales, entre un adjuvant de Freund et un milieu antigénique aqueux, restent encore les références dans le monde entier pour les études en laboratoire. Ils se présentent sous forme d'émulsions eau dans huile (E/H), c'est à dire d'émulsions dans lesquelles la phase continue est l'huile. Or, ces émulsions sont très visqueuses et sont donc difficilement injectables. Elles sont aussi peu stables, puisque des déphasages sont observés quelques jours seulement, après leur préparation.Vaccines made by equal mixing between Freund's adjuvant and an aqueous antigenic medium are still world-wide references for laboratory studies. They are in the form of water-in-oil emulsions (W / O), ie emulsions in which the continuous phase is the oil. However, these emulsions are very viscous and are therefore difficult to inject. They are also unstable, since phase shifts are observed only a few days after their preparation.

Comme adjuvants usuels, il y a aussi des sels de métaux, tels que l'hydroxyde d'aluminium, le nitrate de cérium, le sulfate de zinc, l'hydroxyde de fer colloïdal ou le chlorure de calcium. Parmi ceux-ci, l'hydroxyde d'aluminium est le plus couramment utilisé. Ces adjuvants sont décrits dans l'article de Rajesh K. Gupta et al "Adjuvants, balance between toxicity and adjuvanticity", Vaccine, vol. 11, Issue 3, 1993, pages 293-306 . Ils présentent cependant une faible efficacité immunostimulante et induisent parfois, lorsque ces compositions thérapeutiques sont injectées, la formation de lésions et autres réactions locales, telles que les granulomes, au point d'injection.As usual adjuncts, there are also metal salts, such as aluminum hydroxide, cerium nitrate, zinc sulfate, colloidal iron hydroxide or calcium chloride. Of these, aluminum hydroxide is the most commonly used. These adjuvants are described in the article of Rajesh K. Gupta et al. Adjuvants, balance between toxicity and adjuvanticity, Vaccine, vol. 11, Issue 3, 1993, pp. 293-306 . However, they have a low immunostimulatory efficiency and sometimes, when these therapeutic compositions are injected, the formation of lesions and other local reactions, such as granulomas, at the injection site.

On a découvert plus récemment, que les sels hydrosolubles de métaux divalents ou trivalents, étaient de bons adjuvants de l'immunité. Parmi ceux-ci, le gluconate de manganèse, le gluconate de calcium, le glycérophosphate de manganèse, l'acétate d'aluminium soluble ou le salicylate d'aluminium sont les plus prometteurs. De tels adjuvants sont décrits dans les demandes internationales de brevet publiées sous les numéros WO 96/32964 et WO 98/17311 .It has been discovered more recently that water-soluble salts of divalent or trivalent metals are good adjuvants of immunity. Of these, manganese gluconate, calcium gluconate, manganese glycerophosphate, soluble aluminum acetate or aluminum salicylate are the most promising. Such adjuvants are described in the international patent applications published under the numbers WO 96/32964 and WO 98/17311 .

Comme autres adjuvants de l'immunité, notamment dans le cas de l'administration mucosale, on peut citer les composés sympathomimétiques décrits dans la demande internationale de brevet publiée sous le numéro WO 98/15288 .Other adjuvants of immunity, especially in the case of mucosal administration, include the sympathomimetic compounds described in the international patent application published under the number WO 98/15288 .

A l'occasion de recherches sur la mise au point de nouveaux adjuvants, la demanderesse a découvert que certains agents tensioactifs eux-mêmes, possédaient une efficacité immunostimulante en l'absence d'huiles, et que l'on pouvait ainsi préparer des compositions vaccinales aqueuses, comprenant un ou plusieurs de ces agents comme immunostimulants.In the course of research on the development of new adjuvants, the Applicant has discovered that certain surfactants themselves, had an immunostimulatory efficacy in the absence of oils, and that it was thus possible to prepare vaccine compositions aqueous, comprising one or more of these agents as immunostimulants.

C'est pourquoi, l'invention a pour objet, l'utilisation d'un composé de formule (I) :

        R1-O-(G)x-H     (I)

dans laquelle R1 représente un radical hydrocarboné linéaire ou ramifié, saturé ou insaturé comprenant de 1 à 30 atomes de carbones, G représente le reste d'un saccharide et x représente un nombre décimal compris entre 1 et 5 ou un mélange de composés de formule (I), comme adjuvant d'immunité dans une composition vaccinale comprenant au moins un antigène ou au moins un générateur in vivo d'un composé comprenant une séquence d'acides aminés.
This is why the subject of the invention is the use of a compound of formula (I):

R 1 -O- (G) x -H (I)

in which R 1 represents a linear or branched, saturated or unsaturated hydrocarbon radical comprising from 1 to 30 carbon atoms, G represents the residue of a saccharide and x represents a decimal number between 1 and 5 or a mixture of compounds of formula (I) as an immunity adjuvant in a vaccine composition comprising at least one antigen or at least one in vivo generator of a compound comprising an amino acid sequence.

Par reste d'un saccharide, on désigne pour G, un radical bivalent résultant de l'enlèvement sur une molécule de sucre, d'une part d'un atome d'hydrogène d'un de ses groupes hydroxyle et d'autre part du groupe hydroxyle anomérique. Le terme saccharide désigne notamment le glucose ou dextrose, le fructose, le mannose, le galactose, l'altrose, l'idose, l'arabinose, le xylose, le ribose, le gulose, le lyxose, le maltose, le maltotriose, le lactose, le cellobiose, le dextrane, le talose, l'allose, le raffinose, le lévoglucane, la cellulose ou l'amidon.
